> Synopsis:	low upload speed with pppoe over vlan
> Category:	i386 kernel
> Environment:
	System      : OpenBSD 5.5
	Details     : OpenBSD 5.5-current (GENERIC) #188: Sat Jun 21 13:44:20 MDT 2014
			 deraadt@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC

	Architecture: OpenBSD.i386
	Machine     : i386
> Description:
I have to connect to my ISP, the german Telekom, via pppoe over vlan. When I do this \
on my alix box (described below), I get only a quarter of the possible upload speed. \
The speed is measured from a pc in the lan via website test. The Alix box is \
connected to the local lan (vr0) and my vdsl modem (vr1). A vlan device is set up on \
top of vr1 (vlan 7 vlandev vr1). After that a pppoe device is connected to the vlan \
interface. The connection to the ISP is made once the device has started. The \
download speed is as fast as expected (48MBit), but the upload speed is low (2MBit). \
This happens with 5.5 and also with 5.5-current. Setting up the same configuration \
with another pc (OpenBSD 5.5 / amd64) I get the expected speed results. (48Mbit down \
/ 8MBit up). This pc uses a Intel Card for the modem connection (em0). The upload \
(and download) values are relativ constant, so that i don't expect an error in the \
way of measuring.
> How-To-Repeat:
Connect vr1 device with the modem.
